Room in Clue (4)
I believe the answer is:
hall
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">room in clue</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for hall that I've seen before include "Large house (linked to Dotheboys, Wildfell and Toad)" , "Foyer" , "See 1" , "See 21" , "Large public building" .)
